Hi, I have come across similar problem on other threads but not specifically menus.
I have 2 menus depending on device.
(1) A Desktop menu (using Seydesign my menu)
(2) A Mobile menu (using another but static Seydesign my menu)
A - I would like the (1) menu to show on desktop devices and not on iPad or mobiles.
B - I would like the (2) menu to show on iPad or mobiles devices and not on desktop.
Ok - so my 1st attempt was 2 have the 2 stacks on a page but then turn off the responsive icons for the stack to reflect what devices are being used. Unfortunately this has no affect.
So, after reading a similar thread on here I downloaded Will’s Useful Stack and added the menu stacks into there and selected the hide option in the inspector for devices smaller than (tried many different sizes without anything being hidden).
Eventually I may have to go down the route of designing a mobile only website but a shame as the other aspects of the site are responsive.
